7 Claims.

This invention relates to window gratings adapted for use to preventintruders from entering through windows, and it pertains moreparticularly to a construction in which the bars forming the grating maybe readily moved to and removed from the window barring position.

It frequently happens that the occupants of a home or other building maywish to leave the to windows open but hesitate to do so for fear that anintruder will enter through an open window. To prevent this bars may beprovided across the window but most people object to barred windows asunsightly in appearance.

The present invention therefore contemplates a construction in which thewindow bars may be stored in housings at the sides or top and bottom ofthe window out of sight when not in use, and may be readily moved to thewindow go barring position when their protection is desired.

One important feature of the invention resides in means for supportingthe bars of a window grating for sliding movement from the windowbarring position to a stored position at one or both sides of the windowor at the top and bottom thereof, and in means for locking the bars inthe window barring position.

Another important feature resides in a bar o. receiving housing at oneor both sides or a window and in bar supporting guides adjacent thehousing and adapted to support the bars for sliding movement from thewindow barring position to a stored position in the housing. A furtherfeature 01 the invention resides in supporting guides adapted toslidably receive the loads of the bars and provided with spaem pocketsalong their length to receive said heads and hold the bars .in thewindow position, and in key controlled or other means ior locmng theheads in said pockets.

@ther features of the invention and novel combination oi parts inaddition to the above will he hereinafter-"described in connection with4gp the accompanying thawing which illustrates one good practical dormoi the invention.

The window grating of the present invention may be used in the windowsof the ordinary home or other building and may be readily installed inwindows of various shapes and sizes. The window frame shown, which maybe of the usual construction, has the sides 10, top portion 11, and sillor bottom portion 12, and in this frame are slidably mounted the uppersash 13 and lower sash 14. I

The window grating of the present invention is formed of theindependently movable bars 15 that are mounted for sliding movement fromthe window barring position of Fig. 1 to their so concealed or storedposition of Fig. 2. These bars are shown as provided with heads 16 attheir opposite ends adapted to slide in an upper guide rail 17 and lowerguide rail 18, and each guide rail is preferably given the hollow chans5neled construction shown adapted to slidably embrace the heads.

These guide rails are conveniently made of sheet metal and the upperrail 17 is formed with the spaced upwardly bent edges or ribs 19 havingthe bar receiving slot 20 between them. The heads 16 may slide upon theribs 19 as the bars 15 are moved along the guide 17, and in order toretain these bars in the desired spaced relation" to each other thehead-receiving notches 21 are formed at intervals along the guide railso that the heads may drop in these notches.

The lower guide rail 18 has the channeled construction best shown inFig. 3 and the edge portions of the metal strip forming the channel 18are spaced from each other to provide the bar receiving slot 22. Theguide rail 18 in the constructicn shown is provided at intervals alongits length. with the rectangular holes 23 formed in the lower wall ofthe channeled rail 18 to receive the correspondingly shaped heads 16.The arrangement is such that when a bar 15 is moved along the guiderails 1'7 and 18 to the desired position the upper head 16 will dropinto a notch 21 and the lower head 16 will drop into a hole 23, to holdthe bars in the desired spaced relation to each other.

The bars may be readily locked in the position just mentioned by holdingthe lower 5 heads 16 so that they can not be raised out of the holes 23.This is accomplished in the construction shown by providing the lockingstrip 24 which normally lies inactive within the hollow guide rail 18 atone side of the row of holes 23 as shown in Figs. 4 and 7, and when itis desired to lock the bars in the window barring position it is simplynecessary to shift the strip 24 in the channel 18 to a position in whichit overlies the heads 16 as shown in Fig. 8-. 'Ine strip 24 may bereadily shifted from its inactive position to its active position byproviding it with an operating pin or knob 25 that projects upwardlythrough a diagonal slot 26 formed in the upper wall or the rail 18.. Thestrip 2c is preferably also provided with the inclined surfaces 27 and28 formed at the opposite edges of the bar and adapted to oo-operatewith guide pins 29 and 30, respectively, rigidly secured in the guiderail 18.

The arrangement is such that when the strip 24 is moved in the directionof its length by the knob 25 it will be guided in a diagonal or lateraldirection by the engagement of the inclined surfaces 27 or 28 with thefixed pins 29 or so. The strip 24 may be locked in its bar securingposition of Fig. 8 by a key controlled lock 31 secured to the strip 24and provided with a key actuated bolt 32 positioned to co-operate with afixed pin 29. The key for the lock inserted through ahole 33 in theupper wall of the guide 18. As long as the lower head of a bolt 15 isheld locked in a hole 23 the bolt can not be raised to release its upperend from the corresponding notch 21.

While the mechanism just described constitutes one simple and practicalform of means for locking the bars in the window barring position othermeans to this end may be employed. The locking means may be key orotherwise controlled, and may co-ozoerate with either the upper or lowerguide rail or with both of these .rails as desired.

The guide rail stock 1? and 18 may be supplied in any desired length sothat it may he cut during the operation oi installing a guide rail toconform to the width of the window frame to which it is to be secured,and the upper rail 17 is secured to the top portion of the window Irameby screws 3% while the lower rail 18 is similarly secured to the wondowsill 12.

When the bars 15 are not desired in the window barring position oi l,the loo-Eng strip 24 is unlocked and shifted to its inoperative positionof Fig. 4 so that the bars may be lifted the guide rails to the storedposition at each side of the window. It is desirable to conceal the barswhile they are stored at the sides-oi the window and this isaccomplished in aceord= ance with the present invention by providing ateach side of the window a bar receiving housing 35 which may he formedon sheet metal and given the U-shape in cross-section best in Fig. 4.The housing 35 may be out to the desired length to extend from the upperrail i? to the lower rail 18 and secured to the window frame by screws36. The construction iii trated is such that the entire cratingincluding its supporting rails and housings lies within theoonnneeoithewindowiramesoasnottom out oi the recemes 21 and 23 and movedalong heads and support the here for sliding;

mosses trude beyond the inner face of this frame, and presents a neatappearance.

While in the construction and described the bars 15 extend vertically ofthe window and are stored in the housings 35 at the sides thereof, theguide rails 17 and 18 may if desired be mounted at the opposite sidesot'the window to support the bars in a horizontal position and thehousings 35 may he provided at one or both ends of the windows.

It will be seen from the foregoing that guide rails 17 and 18 andhousings 35 may Le readily cut to fit any window and secured in place bythe screws 34 and 36. The bars 15 may be cut to the required length andthe heads 16 may be riveted or otherwise secured be installed in windowsof a definite size the parts i7, 18 and 85 may be and secured togetherat the factory rectangle frame adapted to it the frame and be securedthereto inside of ing sashes.

When a window is equipped with the are of the present invention theWindow may be wide open either in the day time or ni without the dangeror an intruder ente through the. open window.
